“…To enhance the bandwidth of microstrip patch antennas, a series of techniques has been developed. By stacking parasitic patches to the principal radiator, multi‐resonant wideband response can be attained. Another one is to use thick substrate as well as reactance compensation techniques.…”

A survey of multi‐resonant antennas is comprehensively presented, with emphasis on theoretical framework, design approaches, and practical examples. This article begins with a brief history of the multi‐resonant dipole theory, and then concentrates on the design approaches that have been developed to typical, basic antenna elements, for example, electric dipole antenna, slotline antenna, loop antenna, complementary dipole antenna, and microstrip patch antenna. Design examples for different practical applications are then raised. In final, the multi‐resonant antenna design approach is summarized and compared to some relevant antenna design techniques.

An integral eqnation approach is nsed to str~dy the radiation and matching characteristics of an electrou~agnetically conpled dipole antenna. The clipole is located on top of a generalized anisotropic superstrate, which is itself on top of a gro~~nrletl isotropic substrate. The feeding trans~nission line lies a t the interface between these two layers. The integral equation is solved rigoror~sly using the method of nlon~ents to find the current distribution on both conductors. Nonreciprocal transmission line analysis is then used to quantify how well the n~icrostrip tlipole antl transmission line are matched b.uecl on the current clistril)ntion. Special considerations antl advantages in the design of this type of antenna are discwsetl.

“…However, very limited work has been reported on the design issue of triangular-patch filters, which have received little attention. Triangular resonators were originally introduced by Jhelszajn and P. S. James [4]. Jia-Sheng Hong [5] and B. Strassner [6] reported a development of microstrip triangularpatch resonator filters, in which one transmission zero can be implemented.…”

A dual‐frequency and dual‐linear polarization multilayer microstrip antenna element for array‐antenna applications is presented. The performance of the element was computed using a commercial software based on the finite‐element‐method (FEM) algorithm. A prototype with dimensions based on the simulations was built and tested. Good agreement between the measured and numerical results is obtained. © 2004 Wiley Periodicals, Inc.
